Respectfully, I find most new civics redundant. What does Suzerainty have that's unique from Bureaucracy? They're almost the same in concept and implementation here (allows you consolidate wealth and raw materials in a centralized location); by the description of suzerainty is seems logical that a bureaucracy would have to be in effect for it to work anyways. Representation covers a number of possible government types including republicism and, in my view, your Parliamentary civic.
Regards,
Well, Suzerainty is -20% wonder cost in all cities and Bureaucracy is +50% production only in the capital. So, no functionally they're completely different, one encourages building up a central city while the other building wonders in multiple cities.
Additionally, saying those two are the same civic types in the real world is wrong as a suzerainty is completely different than a bureaucracy. if anything it has more akin to vassalage, though historically both were enacted differently hence the different classifications.
Parliamentary could be argued to be covered under the general term of Representation, though it stands to reason releasing additional civics here is not just for people modding the standard game but also for mods who have edited the civics quite extensively and thus might not have a general 'representation.'
Regardless, the point of these (and any of my python+xml modcomps) is not necessarily how I structured the bonus - calling it parliamentary or suzerainty - but the python itself which people could then copy and adapt to any civic they want.
Despite what you said, the bonus of suzerainty encourages almost the exact opposite building plan than bureaucracy - again ones bonus applying to all cities the other only to the capital. Additionally, dismissing the parliamentary simple because I called it that is foolish because it's bonus is not currently found in the default civics (it acts as an antithesis to police state which increases military production whereas this increases noncombatant production).
Besides, look at the standard civics in the game. Universal Suffrage isn't exactly mutually exclusive to the other government civics (yet it is presented as such). Free Speech really isn't a complete legal system, yet it is its own civic.
